Onshore flow around 15 to 20 knots with occasional gusts to 25kt will persist through early Saturday with 2-4ft seas. Persistent onshore flow has led to increased wave runup along beaches and water levels are expected to be near 3.0 feet above Mean Lower Low Water during high tide cycles over the next few days. A cold front with associated showers and storms are expected to push offshore Saturday evening into early Sunday. Small Craft Advisories will be needed Saturday night into Sunday due to the strong northeasterly winds and building seas developing behind the cold front.
